Emergency Vote by Mail Voting – Authorized Ballot Pick-up
If, during the seven (7) days before an election, you find that you will be unable to vote in person on Election Day, you may request in a written statement, signed under penalty of perjury, that a ballot be delivered to your authorized representative. Your authorized representative will receive your ballot after presenting the signed statement at the San Mateo County Registration & Elections Division.
If you make a mistake, you may get a replacement ballot.

Replacement ballots are a normal part of the Vote by Mail process. Voters may receive additional ballots if they re-register, update their voter registration, or request a replacement from our office. Only the first ballot our office receives will be counted, ensuring NO ONE can vote twice.
If you would like your replacement ballot sent to you by mail, your request must be received by our office no later than a week before Election Day to allow for sufficient mailing time.
How To Mark a Paper Ballot
Marking a paper ballot is the same whether you vote by mail or vote at a vote center. The ballots are the same. The only difference is how you cast your vote: in person or by mail.
